roots are awesome for survivor. gheist too; any SOA messes with many decks' strategies, but a whole wall of it?
Roots have the added bonus of many mediocre 5* so you'll likely be going second a lot of the time in T2.

Good old Hive+Sakrohm is still relevant
I´ve been seeing Robert Cobb decks but i am not sure about their succes rate. (+ i have probablly personally displeasure in those decks)
Roots, nightmare, gheist and vortex are pretty common and strong. The rest i barely see or have no problem with them.
